Well, I just had a whole week off work but I am still not printing. Why, you ask? Because I am a lazy so-and-so. Also because there always seem to be a hundred things that need to be done before I can get to the Reprap work.
I have made some progress though. I have assembled both of my MakerGear Heatcores. They seem to be working perfectly. A small problem with them is that they did not come with the Molex connector that should be attached. I think that the later kits include it (it is shown in the assembly instructions on their website) but mine did not. Remember that I bought my kits last spring so they are from the early lots, things have been improved since then.
I also began assembling the geared extruder. I don't have bolts long enough for some of the assembly steps so I have been cutting lengths of threaded rod and placing a nylok nut on one end. It seems to work fine and it allows me to customize the lengths to whatever I need.
I also discovered another oversight on my part. When I ditched my plan to use a set of used stepper motors for the Mendel I purchased some new ones. Unfortunately they came in a set of three so I don't have one for the extruder. I will have to use one of the second hand motors for this but that means that I have to solve my problem with the gear that is stuck on the shaft. If I can't find a way to remove it without damaging the shaft or the motor I will have to buy another new one and wait for it to arrive. I guess that would not be too serious a problem since I am taking so long with these final steps but I will try to get the old gear off first.
More pictures and some video of the axis moving when I post next time.
